SLAT-FASTENER FOR STRAW CARRIERS.

-PECI]?IJA'IION forming part of Letters Patent No.391,555, dated October23, 18 88.

To all whom it may concern.-

Be it known that I, DANIEL W. PRATT, a citizen of the United States,residing at \Vest Burlington, in the county of Bradford and State ofPennsylvania, have invented a new and useful Improvement inSlat-Fasteners for Straw-Carriers, of which the following is aspecification.

My invention relates to a slat-fastener for straw-carriers, having forits object to provide a simple, cheap, reliable, and easily-operateddevice whereby the transverse slats of a strawcarrier forthrashing-machines may be affixed to the endless belts withoutpuncturing the slat or the belts.

The invention consists in a certain novel construction and arrangement,fully described hereinafter, and pointed out in the claim.

In the accompanying drawings, Figure l is aperspective view of thefastener, showing the manner of attaching the end of the slat to Fig. 2is a transverse central sectional view of the same.

Referring to the drawings, the construction and uses of a straw-carrierand the manner in which it is applied to a thrashing-machine are wellunderstood, and therefore I have not con sidered it necessary toillustrate any portion of the machine.

A designates the fastener, which comprises the rectangular end bands, BB, which are arranged parallel to each other at a distance apart equalto the width of the belt 0, a short section of which is shown passingbetween the bands and the upper and lower longitudinal bars D E, whichconnect and are formed integral with the upper and lower sides of thesaid bands B B. The belt 0 passes over the lower bar, E, the upper sideof which is rounded so as to offer no sharp edges to out or chafe thebelt, and the slat F (only a portion of which is shown in the drawings)passes through the end bands, B B, over the belt and bears on thelatter, thereby holding the same in contact with the bar E.

To prevent a movement of the fastener on the belt and also prevent theslat from slipping out of the bands of the fastener, a setscrew, G, ismounted in a tapped aperture, 9, in the center of the upper bar, D, andbears on the upper side of the slat, thereby clamping the latter andalso the belt in position. It will thus be seen that both the slat andbelt are secured in the fastener by reliable means without puncturing orcutting either or otherwise impairing their strength. Further, the sidesof the slat are embraced by the bands B and therefore are not liable tobe split; and as the bands through which the slats pass are arranged atsome distance apartnamely, a distance equal to the width of thebelt--the slats are prevented from turning or twisting and assuming aposition other than a proper angle to the belts, and therefore thelatter are caused to move at the same speed and the slats are at alltimes perpendicular to the motion of the carrier.

I claim- Asa new article of mauufactu re, the herei udescribed fastenerto secure the slats to the belts in straw-carriers, the same consistingof the rectangular end bands, B B, the integral lower bar, E, connectingthelower sides of the said bands and having a rounded upper side, theupper bar, D, connecting the upper sides of the end bands and having acentral tapped aperture therein, and the set-screw mounted in the saidtapped aperture, substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

DANIEL W. PRATT.
